US20140310311A1 - System and method for concept discovery with online information environments - Google Patents

Abstract

Provided are systems and methods for referencing intent-based taxonomies to enable more natural approaches for users to specify problems to be solved, questions to be answered, and other content requests that can be delivered within online communities. In the medical setting, physicians and medical personnel are accustomed to provide medical information and ask questions of other physicians in the form of a narrative. Narrative medical information can be easy for a physician to define but difficult to process in an online community. The inability to classify such narratives can significantly affect the ability of the physician to obtain answers to his/her question and/or search for material in the community based on his/her question. Narrative statements can be analyzed automatically and standardized concepts returned from medical taxonomies to classify a narrative question. Standardized concepts can also be used to search and/or review material relevant to the question defined within a community.

Description

RELATED APPLICATIONS
• This application claims the benefit under 35 U.S.C. §119 of U.S. Provisional Application No. 61/784,435, entitled “SYSTEM AND METHOD FOR CONCEPT DISCOVERY WITH ONLINE INFORMATION ENVIRONMENTS,” filed Mar. 14, 2013, the contents of which are hereby incorporated by reference in their entirety.
BACKGROUND
• The phenomenon of like-minded people going online to share ideas, trade, or compete is well-accepted. In moving from the physical world to the digital one, users create virtual “communities” where they are bound together by the similarities of their interests or activities, rather than the proximity of their location. These communities can take any number of forms, the most basic being discussion groups, chat rooms, blogs, and forums, which are, in effect, offline communities reincarnated online.
• These online communities can provide powerful sources of information and can also include dynamic creation of information useful both within and outside of these communities.
SUMMARY
• Stated broadly, various aspects of the present disclosure relate to improving access to information generated within online communities and improving the generation of information with the online communities. According to one aspect, various intent-based taxonomies are referenced automatically during creation of content which can occur within an online community or in an environment connected to the online community. Referencing intent-based taxonomies during creation of content within the communities provides unique opportunities to classify information as it is being created and to search within existing communities based on matching an intent defined search.
• According to another aspect, referencing intent-based taxonomies enables more natural approaches for users to specify problems to be solved, questions to be answered, and other content requests that can be delivered within online communities. In the medical setting, physicians and medical personnel are accustomed to provide medical information and ask questions of other physicians in the form of a narrative. Narrative medical information can be easy for a physician to define but difficult to process in an online community. The inability to classify such narratives can significantly affect the ability of the physician to obtain answers to his/her question and/or search for material in the community based on his/her question. In one embodiment, narrative statements are analyzed automatically and standardized concepts are returned from medical taxonomies that classify a narrative question. Standardized concepts can also be used to search and/or review material relevant to the question defined within a community.
• According to some embodiments, medical questions are generated as cases, which organize information on a question, and organize additional information associated with the medical question. Additional case information can also be entered in narrative form, which can also be processed according to identified concepts in medical taxonomies. Further, intuitive user interfaces are provided that facilitate definition of intent during case generation and case searching. According to one aspect, linking user interface displays and narrative data structures associated with intent information enables definition and navigation of intent-based models of the cases. According to one implementation, the intent-based models reflect standardize concepts (e.g., medical diagnoses and medical concept ontologies) facilitating their navigation based on intent. Further, the intent-based models of cases can include additional close-ended selections to further interact with intent-based models of cases.
• It also is realized that conventional online community resources can and do fail to provide answers to question presented within the community. According to one aspect, an active recruitment approach can be executed to ensure answers and interactions occur on a given case and/or question. According to one embodiment, the recruitment approach can be integrated with known or existing online communities to facilitate information exchange and generation. The recruitment approach can be configured to tap resources within an online community but also reach outside of the community to addition resources. According to another embodiment, intent-based models of cases can be used across even language barriers to recruit across the largest knowledge base (e.g., represented by users) possible. Internationally accepted concepts (e.g., SNOMED database) can be used in conjunction with case definition. The resulting case model is configured to be translated through various languages according to the model. Thus the recruitment approach can be augmented by targeting individuals both outside an online community and across languages.

DETAILED DESCRIPTION
• According to one aspect, it is realized that benefits can be obtained by providing users with information targeted to their specific inquiries. One aspect of the present invention is provided by an intent engine (e.g., intent engine102) executed on a computer system as shown inFIG. 1. Theintent engine102 is configured to accept user inquiries, in the form of aquestion104, for example, through auser interface component106. Thequestion104 may contain additional supporting information to aid theintent engine102 in generating anappropriate insight114 directly related to a user's question.Insight114 may take the form of answers to a user's specific question generated by individuals within the appropriate field of expertise. In the field of health care, for example, a question may be related to a suggested prescription for a patient with a specific ailment relating to a patient's skin. The insight generated by the intent engine may then take the form of a suggested prescription for the patient generated by a practicing dermatologist.
• Theintent engine102 is further configured to leverage information provided by anontology component108 to perform a typeahead process for the user while entering text in an open-ended field. The ontology component is configured to organize concepts into a searchable ontology or taxonomy. The ontology component may extract word fragments, entire words, or any combination therein as they are entered to find related concepts in the ontology database. The ontology database may then provide ranked concept suggestions for the user based upon match quality. In the field of health care, for example, the intent engine can be configured to process a question related to a patient's ailment being input as a narrative to find concepts related to the specific ailment and provide suggestions to the user in real time. The ontology component may also match words for the purpose of classifying cases for improved organization and searching.
• In one example, the intent engine may then, through arecruitment mechanism110 recruit individuals for responses to the questions. In one implementation, therecruitment mechanism110 identifies the appropriate background required for a respondent for a given case and solicits responses. The recruitment mechanism may leverage any online network of professionals to locate users. For example, in the field of health care, the recruitment mechanism may access a network of optometrists to pose a question relating to a patient's eyes. The communication architecture for response solicitation may be customized to fit the specific network being accessed or the preferences of an individual.
• In another example, the intent engine may leverage users within an internalonline community112 to generate responses for questions. The online community may be composed of users within a given field and information regarding their respective specialty information. The specialty information related to each user may include their education, occupation, and status as a current practitioner. In the field of health care, the online community may be composed of professionals in the field of medicine. The respective specialty information for each user may contain their sub-discipline within medicine (e.g., Dermatology, Optometry, etc.) including their status as a practitioner (e.g., currently practicing within their given sub-discipline). Theonline community112 may provide information to therecruitment mechanism110 to solicit responses from users within the online community.
• In one embodiment, the intent engine operates within an interactive online information environment which may be accessed by one or more computer systems (e.g., Personal Computers (PCs), Portable Digital Assistants (PDAs), telephones, or other computer system types) using various forms of communication (e.g., Internet, cellular network, etc.) to provide individuals with specific information directly pertinent to their needs. The environment is used to generate, aggregate, and filter information between users in the interactive online information environment. In one implementation, a mobile application tool is provided to permit physicians to locate answers to their questions from the physician community in near-real time, based on anonymous case information provided by the physician.
Example Process
• FIG. 2 shows anexample process200 for generating insights directly pertinent to a specific question. Theprocess200 begins at202 with a user entering a specific question. According to one embodiment, the entry of the question at202 begins an interaction with an information environment (e.g., system100). The information environment provides an online platform for exchanging information between users. In one embodiment, the information environment can facilitate the exchange of medical information. In particular, diagnostic information can be exchanged, discussed and/or evaluated between groups of physicians or other users. The exchanges information can be stored in repositories. The repositories can be referenced in response to a question entered at202 to determine if an insight is available.
• For example, the user may search/browse a database of existingcases204 in order to find a pertinent insight to his or her question. The database of existing case organizes information developed through the information environment. In the medical setting, the database of existing cases can be specifically organized to facilitate search by medical concepts. In some embodiments, the medical concepts can be provided as external references to medical concept ontologies. In one embodiment, the user may search through an open-text field and/or select specific search criteria (e.g., age of patient) from pre-defined lists accessed in the database at204. The system can be configured to contain a typeahead component that matches the user's input into the open-text search field with concepts in an ontology database related to the given field of interest. Additionally, the matched concepts may be displayed to the user to help better define the search. The list of cases matched to both the open-text search field and the specific search criteria may be updated continuously as the user enters information. The supplied matched cases may then be ranked based upon the quality of the match.
• The user may also create anew case206 related to the specific question. In one example, the new case can be created through execution of anintent engine102 on asystem100. Thenew case206 may contain close-ended and/or open-ended information relevant to the user's question. The open-ended information may take the form of a narrative and/or pertinent images. Typeahead functionality can also be executed in conjunction with new case definition, for, example, through execution of theontology component108 that references anontology database208 to identify relevant concepts in the specific field of the question. The system can be configured to provide the relevant concepts to the user through suggestions while the user is entering text into the open-ended fields in the case to assist the user in better defining their question. In addition, the user initiating the case may select restriction criteria for the respondents based upon their specialty information. Thecase206 may then be posed to theonline community210 within the environment. The system can be configured to recruit individuals through arecruitment mechanism110 executed by the intent engine. The system can be configured to leverage individuals from both inside and outside the online community that meet the specialty criteria set forth by the initiating user for the case. Individuals may be incentivized to respond to the case by the system. The incentives provided for a given case need not be static; they can change as parameters associated with the case change (e.g., number of responses, time since last response, etc.).
• Individuals who meet the specialty requirements of the case, referred to as qualified individuals, may respond to the case through multiple methods. Qualified individuals may submit their own responses to the case, submit comments to previously submitted responses, or vote on previously submitted responses. Voting on a response may take the form of an “up-vote” to add credibility to the response to a “down-vote” to reduce the credibility of the response. The responses submitted may then be ranked based upon utility and provided as insight to the user who initiated the case.
• As described above, a user may create a case to generate question specific insight.FIG. 3 shows an example flowchart showing anexample process300 for creating a case according to one embodiment. Theprocess300 begins at302, with creation of a case. In one example, a user with a specific question may create acase302. Definition of a case at302 can include displaying case parameters to the user. In some examples, the user can be requested to provide data in forms displayed to the users associated with specific data fields. For example, a case may contain supporting information in the form of open-ended parameters and/or close-ended parameters. The open-ended parameters may include a narrative field allowing the user to describe their question. The close-ended parameters may include generic classification items related to the type of question in addition to specific criteria relating to the restriction criteria to focus the specialty areas of the respondents. In one example for a health care setting, the cases are implemented in the field of health care. The open-ended parameters may include a “chief complaint” or “CC” of the user along with an associated question such as “what should I prescribe?” or “what is the appropriate diagnosis?” In the field of health care, for example, the system can be configured to also include the open-ended parameter “history of present illness” or “HPI.” The close-ended parameters associated with the case may include patient age, gender, and setting.
• Definition of a case at302 can include processing of word fragments within the open-ended parameters, such as the narrative fields. In one example, definition of the case at302 includes operations for matching concepts from an ontology database with the word fragments. As the word fragments are entered and processed the match concepts can be displayed to the user to achieve typeahead functionality. One embodiment of typeahead functions is described below with referenceFIG. 6 (and shown inDisplay1220 ofFIG. 12B).
• The matched terms in the narrative fields generated at302 may be stored with the case as “tags” used to further classify the case as part of302. The tags in addition to the close-ended parameters may be used to findrelated cases304 to display to the user. According to one embodiment, as the user types a question defining at least some information on the case matching concepts can be delivered and the combined information can be used to search for related cases at304. In one embodiment, matching concepts can be refined and delivered to the user in real time as part of302. Additionally, related cases can be refined and delivered to the user as concept matches are refined and deliver, enabling more refined searches to match related cases as the user's intent becomes better defined. The related cases may be updated continuously in a case repository throughout the case creation process. Any updates to the case repository can likewise be presented to the user as to mitigate duplication in the system.
• Once pertinent information has be defined for the case at302, and any potential matches have been delivered at304, the new case can be submitted at306. In one embodiment, a user enters information at302, reviewed related cases at304, and submits the new case at306 to the system. In response to a new case submission,process300 can continue at308 with recruiting responders.
• In one example, the system can be configured to recruitment individuals to get responses to the new case at308. The system can be configured to leverage an online community within the environment and/or recruit individuals from outside the environment in related professional networks to respond to the case. The act of recruiting at308 can include accessing the qualifications of candidate responders. In one embodiment, accessing the qualifications of candidate responders includes determining qualifications for individual candidate responders and matching their qualifications to the specialty requirements forth in the case. According to one embodiment, inside the online community, user information may be accessed to further determine the best method of solicitation for each user (e.g., email or text message). Execution ofstep308 can include execution of additional processes. For example, recruitment at308 can include execution of a sub-process, instantiation of other processes, which match recruitment criteria to specific responders. The specific responders can be identified and returned by the sub-processes at part of308. In one example, a recruitment sub-process, mechanisms, and/or functionality is described below with respect to process800,FIG. 8.
• After responses directly relevant to the case have been received, the system can be configured to further assign a “score” or utility rating to each response for the purpose of ranking theresponses310. The score may be determined in part by the ranking of the user who submitted the response within the community. The system can be configured to track the history of each user within the online community and assign each user a rank based upon their interactions within the online community. A user's rank may increase by providing valuable responses to cases while a user's rank may decrease by providing poor responses to cases. In addition, the score of a response may also be determined in part by the number of “up-votes” relative to the number of “down-votes” submitted for the given response by other users. “Up-votes” submitted by users represent a user commenting “I concur” with the response while down votes submitted by users represent a user commenting “I disagree” with the response.
• The user who submitted the case may then review the rankedcases312 and determine an appropriate action. In reviewing the responses, the user may submit their final action based upon the responses and the action's associated outcome for the general knowledge users within the environment. In a health care application, the user who submitted the question may give a patient a prescription based upon responses to their inquiry. The user who submitted the question may then post comments relating to the efficacy of the prescription to better educate users within the online community.
• The system can be configured to enable individuals to respond to cases in order to generate new insight relative to a question.FIG. 4 shows an example flowchart showing anexample process400 for responding to cases according to one embodiment. Theprocess400 begins at402, with execution of a search on a database. In one embodiment, an online information system provides access to a database for medical insights. A user within the online community may search thecase database402 to identify cases of interest at404. The system can be configured to monitor case entry/updates through at the database (e.g., at402) and optionally send notifications to a user including cases of interest, for example, determined by their history of interaction with the system or preferences associated with their profile in the online community. According to one embodiment, the system can be configured to store a profile for each user within the community that contains information relating to the user. In one example, the user profile can include their interests and preferred communication methods. The system can be configured to tailor case notifications and subsequent case update notification methods used to contact the user based upon information within their profile in the online community.
• Once a user has identified a case of interest (e.g.,404), or received a notification relating to a case from the system, the user may submit aresponse408 or add an additional comment to a pre-existing response to further define the response. The response may include a narrative response in an open-ended parameter field. In some embodiments, the system provides a user interface including a typeahead functionality to assist the respondent in defining the response. One embodiment of typeahead functionality is described below with referenceFIG. 6 (and shown inDisplay1220 ofFIG. 12B). The typeahead functionality can facilitate concept identification within responses similarly to entry of cases. Consistent concept identification facilitates generation of content within the system that is readily and consistently searchable.
• According to one embodiment, the system can be configured to solicit responses from individuals outside the system (i.e. from other professional networks) by transforming the case into a survey. In one example, the system is configured to generate a survey from information contained in the case and in particular any question being asked. The system can target such surveys to users outside of the network, outside of the online information system, etc. In response to receiving a survey, the individual may then submit a response to the survey in a similar fashion to a user within the online community. In one example, the survey is delivered electronically. The survey can contain links to answers and/or voting options that upon selection will automatically deliver the individuals answer and/or vote. In other examples, the survey can contain access information (including, for example, access credentials) that allow access to a case on the system.
• The system can be configured to allow the user to vote on an existingresponse406 through either up-voting a response or down-voting a response. Up-voting a response may increase the utility score associated with the response and increase its ranking among a plurality of responses submitted to a case. Down-voting a response may decrease the score associated with the response and decrease its ranking among a plurality of responses submitted to a case. The system can be configured to analyze the composition of votes, up-votes and down-votes, and alter the ranking of the respondent within the online community. The user may also flag a response for further review by other users or administrators (e.g., moderators) within the environment.
• In another example, the online community may have a discussion forum that enables users to discuss topics online. In this example, the system can be configured to enable a user to generate arelated discussion forum410 to further discuss the finer points of the case and subsequent responses.
• In addition to case creation and response generation, user may have the option to search or browse the existing cases.FIG. 5 shows an example flowchart showing anexample process500 for searching and browsing cases according to one embodiment. Theprocess500 begins at502, with displaying a list of cases. In one example, a user within the environment may browse or search displayed cases at502. According to one embodiment, the user may select close-ended parameters or enter text into an open-ended parameter, such as a search field, as input into the search to refine the list of entries displayed to the user. The system can be configured to continuously update the list of cases displayed to the user as additional search criteria are selected or entered. The open-ended parameter field in the search may include typeahead functionality where the system references an ontology database to provide suggestions to the user. One embodiment of typeahead functions is described below with referenceFIG. 6 (and shown inDisplay1220 ofFIG. 12B). In addition, the system can be configured to display the matched concepts labeled as tags and used as an additional means of locating similar records within the database, for example, as shown inDisplay1422 ofFIG. 14B.
• The system can be configured to match thecases506 based on all of the entered search criteria. The cases may then be ranked based upon the quality of the match. In one example, the quality of the match may be based on the number of matched tags and classification information items. The ranked cases may then be displayed at508 to the user in addition to statistics relating to the returned cases from the query as shown inDisplay1408 ofFIG. 14A. Execution ofstep506 can include execution of additional processes. For example, matching at506 can include execution of a sub-process, instantiation of other processes, which translate cases within the case database from foreign languages to a preferred language for the viewing user. The cases to be translated can be identified, translated, and returned by the sub-processes at part of506. In one example, a translation sub-process, mechanisms, and/or functionality is described below with respect to process900,FIG. 9.
• The system can be configured to contain therein a typeahead feature to assist users throughout the case creation, search, and response processes.FIG. 6 shows an example flowchart showing anexample process600 for implementing typeahead functionality in one embodiment. Theprocess600 begins at602, with text input. According to one embodiment, the text input is received from an open-ended field parameter displayed in a search interface. In one example, a user inputs text into an open-ended text parameter field at602. The text fragments may be extracted from the open-ended text parameter field while the user is typing into thefield604. The text fragments may include entire words, phrases, or sections of words. The system selects text fragments to analyze based upon their contextual relevance to the case. In the field of health care, for example, a user may enter the following narrative in an open-ended field, “a 35 y/o male with HLA B27-positive inflammatory arthritis.” They system can be configured to match the phrases “HLA B27-positive” and “inflammatory arthritis” rather than trying to match other words that are not contextually relevant such as “a” or “with.”
• The text fragments extracted from the open-ended field may then be matched with an ontology database to findmatching concepts606 pertinent to the specific field of the question. The text fragments recognized by the system for the purpose of matching to an ontology database may include acronyms, colloquial terms, synonyms, and any combination thereof. The list of matched concepts may then be ranked based upon the degree of string match or frequency of the concept in the ontology database608. The system can be configured to also utilize close-ended parameters or other classification tags to improve the quality of the return matches.
• In the field of health care, for example, the ontology database may be the Systemized Nomenclature of Medicine Clinical Terms (SNOMED CT) database. The system can be configured to utilize the close-ended parameter age associated with a case to improve the quality of the returned typeahead matches. For example, the system can be configured to recognize that a user typed “col” relating to a patient under the age of one year. The system can be configured to recognize that there is a higher probability that “colic” is the intended concept rather than “colon cancer.” In another example in the field of health care, a user may enter a synonym or colloquial term relative to the established ontology database such as the phrase “heart attack.” The system can be configured to match “heart attack” with the corresponding term “myocardial infarction” in the SNOMED CT database.
• In one embodiment relating to the field of health care, the system can be configured to re-evaluate medical disclosure in a variety of environments to classify generated content. One example, the generated content can be classified according to concepts. In another example, concept discovery executed by the system can recognize the phrases “male” and “35 y/o” in the narrative “a 35 y/o male with HLA B27-positive inflammatory arthritis” from existing content. The existing content may be modeled into open-ended and close-ended data structures. For example, the data structures may include classification fields relating to the patient gender and age can be populated by the system with the appropriate information (patient gender: “male” and patient age: “35”). In another embodiment, the system can be configured to generate an entire case, including case classification information, from existing content (e.g., any narrative). The source data narratives can be obtained from another existing environment. Another existing environment that can be used as an information source to generate cases is described in commonly owned U.S. Pat. No. 8,239,240, included as Appendix A. Appendix A forms an instant part of this Specification.
• In addition, the system can be configured to make suggestions to the user to disambiguate terms in a given field in process608. In the field of medicine, for example, the term “staphylococcus” could be referring to the “staphylococcus” organism, the substance “staphylococcus toxin”, the disorder “staphylococcus infection”, or the procedure “staphylococcus vaccination.” The system can be configured to pose all of the aforementioned items relating to “staphylococcus” as suggestions to the user to help clarify their input text.
• After the system has determined the list of matching terms in process608, the system can be configured to rank the terms inprocess610. The terms may be ranked based on the number of words matched in a phrase or the number of close-ended parameters matched with the concept. The list of ranked suggestions may be displayed to the user inprocess612 and continuously updated as the user continues to enter text. An illustration of the suggestions displayed to the user may be seen inDisplay1220 ofFIG. 12B.
• The system can be configured to employ a response ranking process to further assist the user discover concepts stored in the online community.FIG. 7 shows an example flowchart showing anexample process700 for ranking responses in one embodiment. The process begins at702, with receiving a case response. An individual may respond to a case through multiple methods at702 as discussed in detail above (e.g., inprocess400 ofFIG. 4). The system can be configured to analyze the status or ranking of the respondent at704, if the respondent is from within the online community. The status or ranking of each member in the online community may be stored in their respective online profile. The ranking of a member in the online community may be determined, for example, by the length of time a member has been active within the online community, level of education relating to their specialty, or time spent as a practitioner within their specialty. Similar metrics may be analyzed from respondents recruited by the system from professional networks outside the system. The ranking of a respondent associated with a response may be displayed to the user through the user interface (e.g.,Display1360C ofFIG. 13).
• The system can be configured to also analyze the composition of votes related to each response at706. An individual responding to a case may optionally submit an up-vote or down-vote with respect to each response. The analysis process may include subtracting the number of down-votes from the number of up-votes received on a response in order to get an aggregate vote count. The aggregate vote count may be displayed to the user through the user interface as seen inDisplay1320B ofFIG. 13. The comments submitted by other individuals with respect to a specific response may also be analyzed at708. For example, the number of comments on a specific response may be determined. Each of the analyzed features may yield a numeric value that can be incorporated into a weighted average to determine a final utility score assigned to theresponse710.
• As discussed, various types of responses can be analyzed to determined utility. In some embodiments, responses can be actively solicited and its utility scored.FIG. 8 shows an example flowchart showing anexample process800 for soliciting responses for cases in one embodiment. The process begins at802, with accessing case information. The system can be configured to access case information at802 to determine what specialty requirements were created by the case creator at804. The case information may also be used to determine the duration that the case has been unanswered or time after the last response to access the urgency of responses needed for the case. The system can be configured to recruit users both inside and outside the online community at806 that are in the generic field of interest to the case (e.g., health care professionals). Resources that exist outside the online community may include networks of professionals in the field pertinent to the case. The system will then determine whether each individual is inside or outside the community at808 and apply a recruitment process based upon their community affiliation.
• If it is determined that a user is within the online community, the system can be configured to leverage the information stored in the user's profile within the system at810. The qualifications of the specific user may be determined if they have the appropriate specialty (e.g., Optometrist) required for the case at812. If the user meets the specialty requirements of the case, the system can be configured to determine the appropriate method to solicit a response from the user at818. The appropriate method may be determined by accessing communication preference information of the user from their profile. The system can be configured to solicit a response for the case from the user at818 based upon their preferences.
• If it is determined that an individual is outside the online community, the system can be configured to communicate with the outside network to determine the specialty of the individual within the outside network. The qualifications received from the outside network may then be compared with the requirements set forth in the case at822. If the individual from outside the network meets the specialty requirements of the case, the system can be configured to solicit a response. The system can be configured to customize the solicitation method for each professional network. In the field of health care, for example, the system can be configured to communicate with a network of doctors of a single specialty who participate in various health care related surveys. The system can be configured to pose the case in the form of a survey to individuals within the outside network to solicit a response.
• Recruitment operations can benefit from translation processes as recruitment may be performed both inside and outside in the environment but also across language boundaries.FIG. 9 shows an example flowchart showing anexample process900 for translating cases according to one embodiment. The process begins at902, with extracting concepts from the case. Concepts from the case, in the form of associated tags or close-ended parameters, may be extracted from a case at902. The concepts can be derived from a concept taxonomy, and in particular, the SNOMED CT database. The extracted concepts may be used to generate a concept model at904. The concept model is an abstract model of the case and its corresponding information that captures the contextually relevant concepts from both the question and any responses. In one example, the concept model is design to include internationally recognized concepts (e.g., medical concepts from the SNOMED CT database). The concept model may then be used as the basis with which to translate the case into a foreign language at906. Theprocess906 may include the direct translation of terms in from the concept model associated with the close-ended parameters and tags. In addition, words may be inserted following the direct translation of the concept model terms to form a coherent case and subsequent list of responses to display to a user. The translated case may then be displayed to the foreign user at908.
General Purpose Computer System
• Various embodiments according to the present invention may be implemented on one or more computer systems. These computer systems may be, for example, general-purpose computers such as those based on Intel PENTIUM-type processor, Motorola PowerPC, AMD Athlon or Turion, Sun UltraSPARC, Hewlett-Packard PA-RISC processors, or any other type of processor.

• Thestorage system1008, typically includes a computer readable and writeable nonvolatile recording medium in which signals are stored that define a program to be executed by the processor or information stored on or in the medium to be processed by the program. The medium may, for example, be a disk or flash memory. Typically, in operation, the processor causes data to be read from the nonvolatile recording medium into another memory that allows for faster access to the information by the processor than does the medium. This memory is typically a volatile, random access memory such as a dynamic random access memory (DRAM) or static memory (SRAM). The memory may be located instorage system1008, as shown, or inmemory system1014. Theprocessor1016 generally manipulates the data within thememory1014, and then copies the data to the medium associated withstorage1008 after processing is completed.

• Althoughcomputer system1002 is shown by way of example as one type of computer system upon which various aspects of the invention may be practiced, it should be appreciated that aspects of the invention are not limited to being implemented on the computer system as shown inFIG. 10. Various aspects of the invention may be practiced on one or more computers having a different architectures or components that that shown inFIG. 10.Computer system1002 may be a general-purpose computer system that is programmable using a high-level computer programming language.Computer system1002 may be also implemented using specially programmed, special purpose hardware. Incomputer system1002,processor1016 is typically a commercially available processor such as the well-known Pentium class processor available from the Intel Corporation. Many other processors are available. Such a processor usually executes an operating system which may be, for example, the Windows-based operating systems (e.g., Windows NT, Windows 2000 (Windows ME), Windows XP operating systems) available from the Microsoft Corporation, MAC OS System X operating system available from Apple Computer, one or more of the Linux-based operating system distributions (e.g., the Enterprise Linux operating system available from Red Hat Inc.), the Solaris operating system available from Sun Microsystems, or UNIX operating systems available from various sources. Many other operating systems may be used, and the invention is not limited to any particular operating system.
• The processor and operating system together define a computer platform for which application programs in high-level programming languages are written. It should be understood that the invention is not limited to a particular computer system platform, processor, operating system, or network. Also, it should be apparent to those skilled in the art that the present invention is not limited to a specific programming language or computer system. Further, it should be appreciated that other appropriate programming languages and other appropriate computer systems could also be used.
• One or more portions of the computer system may be distributed across one or more computer systems coupled to a communications network. These computer systems also may be general-purpose computer systems. For example, various aspects of the invention may be distributed among one or more computer systems (e.g., servers) configured to provide a service to one or more client computers, or to perform an overall task as part of a distributed system. For example, various aspects of the invention may be performed on a client-server or multi-tier system that includes components distributed among one or more server systems that perform various functions according to various embodiments of the invention. These components may be executable, intermediate (e.g., IL) or interpreted (e.g., Java) code which communicate over a communication network (e.g., the Internet) using a communication protocol (e.g., TCP/IP). It should be appreciated that the invention is not limited to executing on any particular system or group of systems. Also, it should be appreciated that the invention is not limited to any particular distributed architecture, network, or communication protocol.
• Various embodiments of the present invention may be programmed using an object-oriented programming language, such as Java, C++, Ada, or C# (C-Sharp). Other object-oriented programming languages may also be used. Alternatively, functional, scripting, and/or logical programming languages may be used. Various aspects of the invention may be implemented in a non-programmed environment (e.g., documents created in HTML, XML or other format that, when viewed in a window of a browser program, render aspects of a graphical-user interface (GUI) or perform other functions).

• Various aspects of this system can be implemented by one or more systems withinsystem1000. For instance, the system may be a distributed system (e.g., client server, multi-tier system). In one example, the system includes software processes executing on a system associated with a user (e.g., a client system). These systems may permit the user to create, submit, view, search, and vote on cases within an online environment.
Example System Architecture
• FIG. 11 shows an architecture diagram of an example system according to one embodiment of the invention. It should be appreciated thatFIG. 11 is provided for illustration purposes only, and that other architectures may be used to facilitate one or more aspects of the present invention.
• As shown inFIG. 11, a distributedsystem1100 may be used to conduct functions of the environment, including, but limited to, the creation of cases, storing case information, determining and storing tag information associated with cases, performing voting actions, and storing user information.System1100 may include one or more computer systems (e.g.,systems1102,1114A-D) coupled by acommunication network1116. Such computer systems may be, for example, general-purpose computer systems as discussed above with reference toFIG. 10.
• In one embodiment of the present invention,system1102 stores user question information in the form of a case in one or more databases (e.g., database1106). Further,system1102 performs associated functions with the user question information and its associated case.System1102 may include a server process (e.g., process1110) that responds to requests from one or more client programs.Process1110 may include, for example, an HTTP server or other server-based process (e.g., a database server process, XML server, peer-to-peer process) that interfaces to one or more client programs distributed among one or more client systems (e.g.,systems1114A-1114D).
• According to one embodiment, client programs may be capable of permitting a user to create, submit, view, search, comment, respond and vote on cases within an online environment. Such client programs may include, for example, any type of operating system and/or application program capable of communicating withsystem1102 throughnetwork1116. In one particular instance, a client may include a browser program (e.g., browser program1120) that communicates withserver process1110 using one or more communication protocols (e.g., HTTP over a TCP/IP-based network, XML requests using HTTP through an Ajax client process, distributed objects, etc.).
• Although it is shown by way of example that a browser program may be used to access the environment by users to perform environment functions, it should be appreciated that other program types may be used to interface a user toserver process1110. For instance, an application program that is specially-developed to manage case data may be provided to permit a user to perform environment functions according to various embodiments of the present invention. The client program may be, for example, a thin client including an interface for managing case data. Alternatively, the client may be a scripted program, or any other type of program having the capability of transferring case data. According to one embodiment, such client programs may, for example, be downloaded and installed over the network. Further, these client programs may be stored and distributed bysystem1102 in the form of one ormore software programs1108.
• In one specific example, the client program may include anapplication program1122 that permits the user to create, submit, view, search, and vote on cases within an online environment. Thisprogram1122, in one embodiment, may be integrated withbrowser program1120 executing onsystem1112D. For instance, theapplication program1122 may include one or more controls that, when selected by the user, perform functions for manipulating case information. These controls may be written in a variety of programming languages, and the invention is not limited to any particular language. In one specific example, the control may be a link that, when selected, performs one or more programmed functions. Such functions may permit the user to create, submit, view, search, and vote on cases within an online environment.
• Information stored in thedatabase1106 may include, for example, case information including, but not limited to, a unique case identifier, a timestamp, a reference ID of the case creator, close-ended case description parameters (e.g., age of patient, sex of patient, treatment setting, etc.), close-ended specialty requirements parameter, close-ended type of question parameter, a chief complaint or brief question open-ended parameter, an additional detail open-ended parameter, a list of tags classifying the case, a case utility score, and a flag. In addition, thedatabase1106 may further include, for example, case response information including, but not limited to, a case identifier, a reference ID of the respondent, type of response close-ended parameter, a response open-ended parameter, a timestamp, a list of tags classifying the response, a response utility score, and a flag. Thedatabase1106 may further include, for example, user profile information including, but not limited to, a user reference ID, a specialty close-ended parameter, a user ranking, a screen identifier, and user preference parameters (e.g., how frequently to be contacted, preferred topics, user's use history etc.).
• This information may be collected from the user in an interface (e.g., as presented by program1122) and stored in the database (e.g., database1106). Additionally, client systems may store a local copy of a user's case information within a local database associated with the client system (e.g.,database1106 located onclient system1112D). However, it should be appreciated that the invention is not limited to storing case and/or user information in any particular location. A client system (e.g.,clients1112A-1112D) may include one or more interfaces through which case information may be presented to the user. In one example, case information and status may be presented in an interface of a browser program (e.g., browser program1120) executing on a client computer system (e.g.,system1112D).
User Interfaces
• The environment and it associated computer system(s) may present various user interfaces for submitting, organizing, and reporting various information related to the environment.FIGS. 12A and 12B are diagrams showing anexample interface1200 of an online system according to one embodiment. The diagram shows a user screen that may be displayed, for example, in an interface of a browser program executing on a general purpose computer system as discussed above with referenceFIGS. 10-11.
• In one embodiment, interface may display a summary page personalized for a user that logs into the system. The system can be configured to display on the summary page of a user his/her name, title, date, time, and status. In addition, the system can be configured to display all the cases the user has authored, commented on, responded to, and voted on along with his/her rank in the online community. The system can be configured to also display statistics relevant to the system, such as the number of users that are online in real-time and the number of users that are registered with the online community.
• In one embodiment, the user interface may interact with a user profile data structure to display user specific information on the summary page. The user profile data structure may include a reference identification data element. The reference identification data element is a user identifier that enables the system to track the user's activity within the online community. In addition, the user profile data may include a specialty data element. The specialty data element contains the list of specialty areas wherein each user is currently practicing. A rank data element may also be stored within the user profile data structure. The rank data element represented a user's status within the online community. In addition, a user preferences element may be stored within the profile data structure. The user preferences data element contains a plurality of preferences associated with the user (e.g., how to be contacts, preferred topics, etc.). A screen identifier element may also be stored within the user profile data element. The screen identifier element may include a personalized image used within the system to represent a user to other online community users.
• FIGS. 12A and 12B show anexample interface1200 for creating a case according to one embodiment. For example, an environment may support respondent specialty restrictions for a given case. In theexample interface1200 relating to case creation, the system allows the user to select thenecessary qualifications1202A and1202B that each respondent must possess in order to submit a response to the case. The system further allows the user to submit close-ended parameters to classify thecase1204A-1204C (e.g., patient age, patient gender, patient setting). The user interface may contain an interactive drop-down menu to enable a user to select a question or, alternatively, enter their ownspecific question1206 into an open-ended parameter. The system accepts a description of the question or alternatively a “chief complaint”1208 as an unstructured text parameter. The user interface may include a second unstructured text field to enable a user to add additional information to further define thequestion1210. In the field of health care, for example, the second unstructured text field may be a “history of present illness”field1210. The user interface may also allow the user to post pictures orfiles1214 corresponding to the case. In one embodiment, the interface may operate on a mobile device with camera functionality. The user interface, in this example, may allow the user to take a picture with a mobile device and directly attach the image to thecase1216. The user interface can also be configured to allow the user to submit1212 the case to the system.
• In one embodiment, the user interface may interact with a case data structure stored within the system to accept user input during case creation. A restriction requirement data element may be stored in the case data structure. The restriction requirement data element may store a plurality of related specialties determined by the user within which each respondent must practice. The case data structure may, in addition, contain close-ended classifying information data elements input by the user. In the field of health care, for example, the classifying information data elements may include a patient's age, gender and setting. A question data element may be stored as either an open-ended or close-ended parameter in the case data structure. The open-ended variant of the question data element enables a user to enter a custom question while the close-ended variant of the question data element enables the user to choose the question from a list. In one example data structure, the system can be configured to store question description information, or a chief complaint, in a first unstructured text data element. The system can be configured to store, in addition, additional description information, or history of present illness information in a health care example, relating to the case in a second unstructured text data element.
• The typeahead functionality, as previously discussed above inprocess600 inFIG. 6, may be implemented to make suggestions to the user when entering text into any open-ended text parameter, for example, thechief complaint1208 andadditional information1210 fields. The suggestion matched by the typeahead feature may be displayed to the user via alist box1220 composed of concept suggestions that match the entered text fragments. Matched words may be emphasized (e.g., underlining, highlighting, display intensity, bold, color, etc.)1218 by the system to display to the user as tags created by the system for the purposes of classifying the case. The emphasized words may also focus the user on the terms identified within the narrative associated with a matched concept. In addition, the system can be configured to list the matched concepts with a given tag when a cursor is placed over the emphasized word. In one embodiment, the system can be configured to store matched terms from the chief complaint and/or additional information fields in a tags data element associated with the case data structure. According to one embodiment, the system can be configured to perform concept matching independent of typeahead functionality. The matched concepts can be emphasized (e.g., underlining, highlighting, display intensity, bold, color, etc.) to the user.
• FIG. 13 shows an example interface for responding to a case according to one embodiment. For example, an environment may support responses to case questions posed to the system. Theuser interface1300 may display the relatingcase information1310 to the user to evaluate the case and form an appropriate response. The case information may contain all of the close-ended and open-ended parameters associated with the case that were entered during its creation from the case data structure. In addition, information related to each pre-existing response may be displayed to theuser1340. The pre-existing response information displayed to the user may include, but are not limited to, therespondent1360A, the specialty of the respondent1360B, the ranking in the online community of the respondent1360C, the response submitted by therespondent1340, theresponse utility score1350, and the number of votes on aresponse1320B.
• In one example, the user interface may accept responses from a user in the form of votes on a pre-existing response. The system can be configured to enable up-voting or down-voting a response as seen by the uparrow1320A corresponding to an up-vote and downarrow1320C corresponding to a down vote. The total number of votes or the sum of the up-votes minus the sum of the down-votes may be displayed1320B between theup arrow1320A and thedown arrow1320C. In addition, the user interface may accept a narrative response in an open-endedparameter1370. The system can be configured to optionally offer suggestions to the respondent while writing their own response and emphasize/tag matchedconcepts1380 through a typeahead process described inprocess600 inFIG. 6.
• In one embodiment, the user interface may interact with a response data structure stored within the system to accept user input during response submission. A user reference information data element may be stored in the response data structure. The user reference information data element identifies the respondent within the online community. The response data structure, in addition, may contain a response description data element. The response description data element is an unstructured text field that stores a user's submitted answer or their comment on a pre-existing answer. In addition, the system can be configured to store matched concepts within the response description in a tags data element associated with the case data structure. The response data structure may also include a score element. The score element characterizes the utility of the response.
• FIGS. 14A-14B show an example interface for searching or browsing cases according to one embodiment. For example, an environment may support searching and browsing capabilities for the case database. Theuser interface1400 may allow a user to enter search criteria into the open-endedsearch bar1402. The user interface will continually update the cases displayed to the user in addition to the statistics derived from all of thematching cases1408. The displayed matchedcase statistics1408 may include age, gender, and patient setting. The user may then select close-ended parameters either alone or in combination with the open-ended search bar. Thespecialty1404 may be selected to narrow the field of interest. The question type may also be selected1406. In a health care application, the type of question may relate to prescriptions (i.e. Rx) or optionally diagnoses (i.e. Dx) or a custom user created question.
• The cases displayed may be sorted1410 by various options which may include case rating, time of last response, and number of responses. The user interface may also display the number ofvotes1412 andanswers1414 relating to each case. In addition, generic case information may be displayed to the user such as the time oflast response1418, thespecific question1418, and selected tags associated with thecase1420. The presence of tags within a specific search may be viewed graphically in theinterface1422 and sorted by frequency. In addition, specific tags may be selected to further narrow and define the search responsive to a user's selection.
Interactive Online Information Environment
• In one embodiment, an online environment is created, forming an interactive online information environment. The environment may include a community of users that together, function to exchange information. In such an environment, a community is created by one or more rules influencing the behavior of a plurality of users. According to one embodiment, the rules adhere to the basic drives and ambitions of the users and channel the interested users back into the environment. In particular, rules may be designed that provide incentives (and disincentives) for certain types of behavior. Optimally, the rules encourage users to submit original questions, respond to questions, and encourage others to review the responses to foster consensus. In one embodiment, the rules function without external (other than users) or moderator intervention.
• The overall environment may be driven by several processes. One process permits users to take independent actions, and the user's independent actions affect the environment. Therefore, the environment can be self-perpetuating. Further, the environment can create its own content, as users define and vote on the questions and responses of others. The environment may be self-regulating, for instance, as users determine the value of the questions and responses. One method of the driving of the environment involves recruiting new users as individuals within the environment pursue their own interests.
• The environment can be manipulated to fit the interests of those that run the environment (e.g., a system operator) by generating valuable data for third parties that consume information generated by the environment. One method for ensuring that valuable data is generated includes creating rules that promote the creation of valuable data and by integrating adjustable variables into the rules.
• Such an environment may be applied to different problems, markets, and subject areas. One such application is health care, and the field of medicine in general. The health care industry is a good application of such a system, as there are a number of readily available customers for the information generated by the environment. For instance, the environment may permit physicians to further their understanding of uncommon ailments by posing a question to specialists within the health care community. Another application includes tracking of prescriptions for specific ailments to provide pharmaceutical companies insight as to what treatments physicians most often prescribe.
• The environment can successfully exploit multiple behaviors of various users, such as greed, drive for collaboration, and humanitarianism. Because there is a continuous need for information, the information of the environment is self-renewing and replenishes itself continuously. Although health care is one application of such an environment, it should be appreciated that the invention is not limited to any specific field, and may be applied to other information-sharing situations where collaboration facilitates information that has value.
• In one example application of such a system, a value of a physician's response to a user's specific question (modeled in the system in the form of a “case”) in the system is determined by how many people agree or disagree with the response at any given moment. Physicians from diverse backgrounds are incentivized to submit responses and to corroborate or dispute those responses in the system, providing a resultant method by which clinical data may be gathered. Further, a ranking of users may be determined, used in part to determine a utility value of responses, and to incentivize desired responses and/or voting behavior.
Example Environment
• In one example implementation, a system is provided that permits a user to perform a number of actions relating to questions submitted by users. In one particular embodiment, the user may submit question specific responses, comment on existing responses, or vote on existing responses. In one example implementation, the question may be represented in the system in the form of a case. In the example, the case is a construct that permits a question to be shared and viewed by other users as well as allowing the system to track the question as it progresses through the environment.
• A user may create a question by creating a case that describes the question. In one example, the case includes a number of parameters including close-ended and/or open-ended parameters. In one example for a health care application, the close-ended parameters may include patient gender, age, and setting, and the open-ended parameters may include a narrative and pictures. In another example, the length of the narrative of the question associated with the case may be any length (e.g., no minimum or maximum length). In other words, the question description can be as long as a user wants, or as short as he/she wants.
• According to another embodiment, the case may also include classification information, either part of or separate from the case, the classification information indicating an organization of the case such that the case may be easily located. In another embodiment, it is appreciated that the system can be configured to match concepts from an ontology database to the user's input into an open-ended text field, such as the narrative field in a case. The system can be configured to create tags based upon the matched concepts in the case narrative to aid in organization and classification. Because cases have associated tags, cases with similar or the same tags may be located more easily by a system or an associated user. Further, actions may be performed in response to tag information, such as alerting a user when a case having a particular tag is created, locating similar cases using tag information, and other actions relating to the organization and control of cases.
• According to another embodiment, the system can be configured to present to the user an interface that provides real-time feedback of classification information as the user enters information associated with the cases. For instance, a list of related cases may be presented to the user, and while the user enters description information of the case, the list of the most relevant cases may be changed in response to the entry of the user. In this way, the feedback permits users to create better cases (by seeing already existing cases in the database) and also permits the user to easily locate similar cases (e.g., by selecting cases presented in real-time to the user in the interface).
• Also, the user may be permitted to express an opinion on an existing question by voting or commenting on an existing response. In another embodiment, the user may be permitted to submit a response to the question. The response may include a narrative to describe and qualify the response.
• In one embodiment, when a user creates a case, the user classifies the case. The classifications may include but are not limited to classifying the case as a particular type of question. There may be more or less classification types, depending on the application, but are generally referred to herein as a question. The cases may also be classified by the user and/or system. For instance, tags or other classification information may be associated with a case.
• In one embodiment, the online system can be configured to assign each case a “value.” Depending on the subject matter of the question, the case may be assigned an initial value, which may be adjusted depending on the market value of the case (e.g., the value of the case as determined by a bid process involving interested information consumers) and/or the opinions (e.g., in the form of votes) set forth by other users relating to the case.
• The values may be assigned in real-time, when the case is created, however, the initial value can be revisited with the value on any given case increased or decreased as needed to promote the health of the environment. Health of the environment may be monitored, for example, by measuring a number of votes received in a particular area or case. Once submitted, any other users can vote on a case or submit an alternative answer with a case as well as forward the case to any other users inside or outside the environment.
• The user may also be “charged” a currency for voting on a case. For instance, the user may be provided a particular number of points or other credit, and decremented each time the user votes on a case. The user's credit may be increased in response to a positive behavior exhibited by the user in the environment (e.g., the user creates cases, provides early votes, becomes an expert in a particular field, etc.). In this manner, the system rewards positive behavior and encourages participation in the environment.
• The environment may have a number of different types of consumers and providers of information. Users that provide questions may or may not be charged a fee for accessing the environment, but in one embodiment of the environment, information consumers are charged for their use and access to the questions and responses provided by and ability of the system to establish communication between others. In one example system, consumers may be charged a subscription fee to search/browse cases within the environment. Such fees may be used, for example, to maintain the environment. In another example system, the results of a submitted question may not be shown to the public. In yet another example, the results of the case may be the exclusive property of the consumer for a fixed period of time (e.g., 60 days) after which, the results are published to the environment.
• In such an environment, it is appreciated that there may be trade-off between consensus and early response, but according to one embodiment, such a model according to various embodiments may perform more quickly and accurately than conventional survey models. In one such system, a customer/information consumer may be permitted to set predefined “triggers” that alert the consumer if/when a user (e.g., a physician) makes a question of interest. The consumer may then be able to identify to the environment how many users would need to vote on that question for the corresponding responses to be valuable to them. The system can be configured to determine the current voting rates for the desired population of users, the amount of incentives (e.g., money) that needs to be applied, and when the consumer agrees, that consumer may be granted exclusive access to the result information. Optionally, users that vote on the question may be made available to the consumer for direct contact, permitting the consumer to more quickly and effectively reach a targeted group that has the necessary insight and/or experience in a given area.
• This invention is not limited in its application to the details of construction and the arrangement of components set forth in the previous description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” “having,” “containing,” “involving,” and/or variations thereof in this document, is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Such terms are to be construed as open-ended, that is, to mean including but not limited to.
• Use of ordinal terms such as “first”, “second”, “third”, etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term) to distinguish the claim elements.
• Having thus described several aspects of at least one embodiment of this invention, it is to be appreciated various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure, and are intended to be within the spirit and scope of the invention. Accordingly, the foregoing description and drawings are by way of example only.
